I realized that I needed a video. But why whiteboard?..

“The simpler the object is, the less effort the brain needs to process and relate to the image,” explains The Draw Shop’s Neuroscientist and Ph.D Carla Clark. “Applying this neuro-psychology to whiteboard videos vs. talking heads, we are wired to pay more attention to the simplicity of whiteboard videos. All the while, this frees up processing power to digest the narrative. The use of the artist’s hand in a whiteboard animation provides a vivid visual progression, where viewers consume this information one step at a time in a logical sequence — which keeps the viewer engaged and prevents the wasteful wandering of attention.”

Four Reasons Why Your Next Marketing Move Should Be A Whiteboard Animation Video

Whiteboard is the best choice in terms of price / quality. You can shoot a “talking head” on a good smartphone for free. But, first, you will have only 8 seconds to capture the viewers attention. Secondly, according to the research results, the whiteboard allows to assimilate information by 49% more effectively. Third, animations are three times more likely to be reposted in social media than videos

You can hire professionals who will shoot you a good video. But you should be prepared for equally “good” prices.
Quality video-is:
1) properly selected “location”;
2) an experienced Director;
3) well-tuned light;
4) a talented operator…
Thus video, by definition, is more expensive
But you don’t need the video itself!
You need to convey certain meanings to the audience. So why you should pay more if you can make a cartoon?
